/*** globals.h - global variables/needed across modules ************************
|
|
*
|
|
* Copyright (c) 1988-1990, Microsoft Corporation. All rights reserved.
|
|
*
|
|
* Purpose:
|
|
* Globals.c is the routine in which global variables reside. Globals.h mirrors
|
|
* the declarations in globals.c as externs and is included in all routines that
|
|
* use globals.
|
|
*
|
|
* Notes:
|
|
* This module was created for an interesting reason. NMAKE handles recursive
|
|
* calls by saving its global variables somewhere in memory. It handles this by
|
|
* allocating all global variables which have value changes in each recursive
|
|
* in adjacent memory. The routine called recursively is doMake() and before it
|
|
* is called the address of this chunk of memory is stored. When the recursive
|
|
* call returns the memory is restored using the stored address. startOfSave and
|
|
* endOfSave give the location of this chunk. The reason this method was opted
|
|
* for is that spawning of NMAKE would consume a lot of memory under DOS. This
|
|
* might not be very efficient under OS/2 because the code gets shared.
|
|
*
|
|
* Revision History:
|
|
* 15-Nov-1993 JdR Major speed improvements
|
|
* 04-Apr-1990 SB Add fHeapChk
|
|
* 01-Dec-1989 SB Made some variables near and pushed some into saveArea
|
|
* 19-Oct-1989 SB variable fOptionK added (ifdef SLASHK)
|
|
* 02-Oct-1989 SB add dynamic inline file handling support
|
|
* 24-Apr-1989 SB Added ext_size, filename_size, filenameext_size &
|
|
* resultbuf_size for OS/2 1.2 support
|
|
* 05-Apr-1989 SB made revList, delList, scriptFileList NEAR
|
|
* 22-Mar-1989 SB removed tmpFileStack and related variables
|
|
* 16-Feb-1989 SB added delList to have scriptfile deletes at end of make
|
|
* 21-Dec-1988 SB Added scriptFileList to handle multiple script files
|
|
* removed tmpScriptFile and fKeep (not reqd anymore)
|
|
* 19-Dec-1988 SB Added fKeep to handle KEEP/NOKEEP
|
|
* 14-Dec-1988 SB Added tmpScriptFile for 'z' option
|
|
* 30-Nov-1988 SB Added revList to handle 'z' option
|
|
* 23-Nov-1988 SB Added CmdLine[] to handle extmake syntax
|
|
* made pCmdLineCopy Global in build.c
|
|
* 21-Oct-1988 SB Added fInheritUserEnv to inherit macros
|
|
* 20-Sep-1988 RB Clean up.
|
|
* 17-Aug-1988 RB Declare everything NEAR.
|
|
* 06-Jul-1988 rj Ditched shell and argVector globals.
|
|
* Put all ECS declarations as macros in here.
